Note that the amount of available memory is less than the "round number" suggested by the hardware configuration. For instance, "base" nodes do have 128 GiB of RAM, but some of it is permanently occupied by the kernel and OS. To avoid wasting time by swapping/paging, the scheduler will never allocate jobs whose memory requirements exceed the amount of "available" memory shown above. | Note that the amount of available memory is less than the "round number" suggested by the hardware configuration.

All nodes have local (on-node) temporary storage. GPU nodes | All nodes have local (on-node) temporary storage. Compute nodes (except GPU nodes) have two 480GB SSD drives, for a total raw capacity of 960GB. GPU nodes have either an 800GB or a 480GB SSD drive. Best practice to access node-local storage is to use the directory generated by [[Running jobs|Slurm]], $SLURM_TMPDIR. | ||
